HOT-AIR HEATING SYSTEM.

Specification of Letters Patent.

Patented June 10, 1919.

Application filed February 13, 1917. Serial No. 148,357.

To all whom it may concern Be it known that I, WILLIAM G. FELToN, acitizen of the United States, residin at Wakernan, in the county ofHuron and tate of Ohio, have invented certain new and usefulImprovements in Hot-Air Heating Systems, of which the following is aspecification.

My invention relates to improvements in hot air heating systems, and itconsists in the construction, combination, and arrangement of parts,herein described and claimed.

One object of this invention is the production of a hot air heatingsystem which includes primary and secondary jackets spaced apart andfitting over the furnace, together with means for causing the air to bepassed within the jackets and over the furnace for heating the air.

Another object of this invention is the )roduction of a hot air heatingsystem which includes primary and secondary jackets positioncd over afurnace, together with fresh air supply means carried by the secondaryacket in alinement with the top of the primary jacket, while deflectorplates are fixedly secured between the two jackets, and openings areformed in the primary jacket out of vertical alinement with the ends ofthe deflector plates, whereby air is passed into the device and causedto pass over the greatest surfaces of the primary jacket and the furnacefor being heated.

Other objects and advantages of the invention will appear from thefollowing specification, reference being had to the accompanying drawingin which:

Figure 1 is a vertical section of a furnace illustrating the embodimentof my invention, and

Fig. 2 is a plan view of one of the floor registers.

By reference to Fig. 1 of the drawings it will be observed that I employa furnace 1 which may be of any ordinary construction and is providedwith a smoke flue 2. The products of combustion are conveyed to theouter atmosphere through the flue 2. Access may be had to the furnace 1through a suitably arranged door, (not shown), the various jackets,hereinafter to be described, being similarly provided with openings sothat the door in the furnace 1 may be reached.

Disposed about the furnace 1 is a primary jacket 3 which is spaced fromthe furnace 1 at approximately equal distances. The upper portion of theprimary jacket 3 converges as at 4 so as to more readily receive the hotair distributing ipes 5 which are joined therewith in any suitablemanner. Openings 6 are formed in the lower portions of the primary jackct 3 wherein cold air is adapted to pass into contact with the hotair furnace 1 Where it is heated.

Arranged about the primary jacket 3 is a secondary jacket 7 which mayrest on a floor as shown in Fig. 1 so that exterior communicationthrough the secondary jacket 7 is closed. The secondary jacket 7 is alsospaced at approximately even distances around the primary jacket 3 andreceives at places coinciding with the hot air distributing pipes 5,cold air return pipes 8. The cold air return pipes 8 are thuscircumposed on the hot air distributing pipes 5 and form7 5 hot airinsulating jackets therefor.

Fresh air is supplied through the secondary jacket 7 by means of a fine9 which leads to an opening 10 in an adjacent wall. A damper 11 in thepipe 9 is used to either partly or wholly close the fine member when itbecomes desirable to do so. The line 9 discharges through the secondaryjacket 7 at the top thereof so that the air can pass through the acket 7and will strike the top of the primary jacket 3 and be diverted towardthe sides of the jacket 7 where it flows downwardly in the channel orchamber formed by the walls of the primary and secondary ackets 3 and 7respectively.

The hot air distributing pipes 53 and the circlnnposed cold air returnpipes 8 lead to floor register plates The hot air from the pipes 5 isdischarged through the register plates 12 centrally thereof from whencethe hot air rises and fills the room. The cold air in the room beingheavier than the. latter naturally moves toward the floor of the roomand is caused to pass through the outer portions of the register plates12 and to enter the cold air return pipes 8. It will be observed thatthe adj acent portion of the cold air return pipes 8 is flared outwardlyas indicated at 13. The purpose of this construction is to takeadvantage of the entire remaining portion of the register plates 12unoccupied by the centrally disposed hot air distributing pipes 5.

Deflector plates 14 are arranged between the inner and outer jackets and7 adjacent to the outlet of the cold air return pipes S into the jacket7. These deflector plates 14 are inclined downwardly so that theincoming cold air from the pipes 8 may more readily be directed into thepassage or channel between the inner and outer ackets.

The construction of the device having been explained the method ofheating is as follows:-The cold air entering the flue 9 and striking thetop of the primary jacket 3 will be diverted toward the edges thereof.The current of cold air descending by way of the pipes 8 will meet thecurrent of air discharged from the flue 9 and merge into asingle currentwhich will strike the de' flector plates 14 and pass downwardly into thechamber or channel between the primary and secondary jackets 3 and 7. Inpassin downwardly the cold air in the pipes 8 wi be preheated. This isso because the greater heat from the furnace 1 naturally rises towardthe top and forms an area where the greater heat is present.

The preheated air in the channel between the inner and outer jackets 3and 7 then passes to the openings 6 at the bottom of the primary jacket3 whereupon it comes into immediate contact with the furnace 1. Inflowing upwardly, the current of air is heated to a still greater degreeuntil it reaches the place of ingress into the hot air pipes 5.

The hot air in flowing out of the register plates 12 toward the upperportion of the room above the register plates and the cold air adjacentto the floor of the room flowing into the outer portion of the registerplates 12, causes a circulation of air in the room which is always warmand fresh.

Having thus described my invention what I claim is:

In a hot air heating system, the combination of a fuinace, a primaryjacket fitting about said furnace and being spaced there from, saidprimary jacket having openings formed therethrough adjacent its lowerportion, a smoke flue leading from said furnace, a secondary jacketpositioned about said primary jacket, deflector plates carried by saidprimary and secondary jackets, the ends of said deflector plates beingspaced apart out of vertical alinement with the openings formed throughsaid primary jacket, a fresh air flue connected to the top of saidsecondary jacket, in vertical alinement with the top of said primaryjacket, thus causing the cold air to be first injected on the top of theprimary jacket and then deflected by said plates around the primaryjacket and pass through the openings in the primary jacket and be heatedby the furnace, hot air pipes leading from the primary jacket and coldair pipes communicating with the secondary jacket.

In testimony whereof I allix my signature in presence of two witnesses.
